JASPER TUDOR, second son of Owen Tudor and Queen Catherine, sirnamed of Hatfield, the place of his nativity. He was by King Henry VI, his half-brother, created first, Earl of Pembroke, and to have place in parliament next after his brother Edmund. But King Edward IV attaining the crown, this Jasper was attainted, and William, Lord Herbert, created Earl of Pembroke in his room, his patent expressing, that he had that honour for expelling Jasper the rebel.

But fortune revolving, by the recovery of the crown to king Henry VI, this Jasper was restored to the earldom of Pembroke, anno 1470; but being taken prisoner at Barnet-field soon after, he lost his earldom a second time, which being surrendered by the second William Herbert to king Edward IV, that king gave it to his son prince Edward, who enjoyed it during life.

King Richard III held also this earldom till the time of his death, at Bosworth-field, when Henry VII attaining the crown, he not only restored this Jasper, his uncle, to the earldom of Pembroke, but likewise advanced him to the dignity of Duke of Bedford, in the 1st of his reign. He was also, by the same king, constituted high steward at the coronation of his queen, Elizabeth. The next year he made him lieutenant of Ireland for one year, and in the 5th of his reign, granted him the office of earl marshal, and to the heirs male of his body.

He had a natural daughter, named Helen, who was married to William Gardiner, esq. of London, by whom she had issue, Stephen Gardiner, lord Prior of Tinmouth, and afterwards lord bishop of Winchester, whose fame in the bloody annals of persecution, during the reign of Queen Mary, may be well remembered.
